The movement device is used in order to verify the mechanical endurance of diverter cartridges (cartridges with two separate outlets and one closed position in the centre).
It includes the torque motor used for endurance tests of single lever mixers. A telescopic universal joint connects the flow control under test to the torque motor. A calibrated hydraulic resistance mounted on the tap limits the flow-rate value as indicated in the standards. The test method consists in subjecting the component to a specific number of cycles between the two open positions and the central closed position; angular speed is defined by the standards. The faucet can be supplied by hot and cold water alternately or with the same water for the entire test.
The software allows to control: the rotation angle, the angular speed and torque.
